As you have the technical ‘know-how’, take a look at your DNS settings - particularly on your mobile device - to see not only the trackers on websites and e-mail links, but also mobile apps. Look at the data brokers. Then re-affirm its ridiculous paranoia…
“Total” is a slog. It’s largely unavoidable but preventative measures, particularly privacy, go a long way.
I actually quite enjoy it and don’t find it too difficult. Alias e-mail addresses is a very good idea, as is unique passwords for each sign-in. This is great for security. However, doesn’t do as much for privacy in isolation where other identifiers can be linked.
Right now, John and Jane use their payment card at a lingerie store for some battery operated merchandise and check in to a hotel for a ‘private’ rendezvous. However, their bank knows where they’ve purchased and where they’ve been and where they’re staying, the store knows what they’ve purchased and provide a receipt to their e-mail address. Their devices know every intimate detail. In fact, depending on where they met and how they communicate, other organisations will know what they talk about and certainly how often they’re in touch. Whose business is it what John and Jane get up to?
So true. Fraud from AI is huge and it can only get worse! Then when you look at future-proofing with quantum computing, look at the exploitation opportunities. Thankfully, companies are getting ahead with it for things like communication (iMessage/Signal etc).
Currently, Ofcom and U.K. networks aren’t doing enough about CLI spoofing either. Then you have the additional issue of anti-spam apps that may purport to be ‘doing good’ but actually helps fraudsters. Spoofing/quantum is kinda a whole other story here and probably not what the OP has stated their use-case. Explicitly anyway.
Do all you can with best efforts. You’ll struggle to get “Total” but that’s okay.
